English term

cross-gradient

English to Polish Science Geology
The risk of site contamination resulting from the identified historical and present offsite sources is assessed as low. The nearest identified potential sources (historical, currently empty, heating oil UST, small operated heating oil ASTs, coal storage yard) do not present significant risk, and no indications of spills were identified or reported by the site. The identified potential sources are located likely cross-gradient from the investigated area. Lack of shallow groundwater layer means in addition that there is no migration pathway to transport potential contaminants.

okay thanks again for your help Frank :)
Frank Szmulowicz, Ph. D. Apr 10, 2018:
Uważam, że obie odpowiedzi są poprawne w danym kontekście, zwłaszcza odpowiedź nawiązująca do wód podziemnych. Istnieje także powiązane pojęcie spadku (gradientu) hydraulicznego, tutaj prostopadle do kierunku gradientu hydraulicznego. Jest wiele wyboru.
dreamscar (asker) Apr 10, 2018:
thank you
Frank Szmulowicz, Ph. D. Apr 10, 2018:
I will come back to this line of thought later.
Frank Szmulowicz, Ph. D. Apr 10, 2018:
Więc innym określeniem cross gradient jest prostopadle do kierunku spływu wód podziemnych.
Frank Szmulowicz, Ph. D. Apr 10, 2018:
Perhaps a more technical answer would involve the direction of groundwater flow; however, if often follows the geographic topology.

I think the original question was for a definition of 'hydrologically upgradient and down gradient' and how that might relate to topography. Hydrologically upgradient and downgradient refer to the direction of groundwater flow. Often groundwater flow mimics topography, but not always. If you have water table data, then you can determine a flow direction. If data are unavailable, then an assumption that groundwater flow mimics topography is a good, but not safe, bet. In my experience, groundwater flow direction reversal has been a good sign that I'm looking at a perched water table. I'm not doubting the other examples discussed above, but often the explanation is as simple as, 'there is no regional flow.' And, yes, a geologic and hydrogeologic education (and I'm not talking about a course or two) should be a requirement for attempting to interpret the subsurface.

w poprzek/prostopadle do nachylenia

The other choices are upgradient and downgradient.

• Locating monitoring points downgradient from a site prior to any facility

Drenaż instaluje się w zboczu terenu powyżej konstrukcji oporowej, możliwie równolegle do jej trasy i możliwie prostopadle do kierunku przepływu wód gruntowych.

W zaistniałej sytuacji można zastosować jedynie działania mające na celu skanalizowanie spływających, zanieczyszczonych wód poprzez wykonanie bariery w postaci rowu (podłużnego zbiornika) zorientowanego prostopadle do kierunku spływu wód.

Amplituda sezonowych wahań zwierciadła wody wynosi w dolinach ok. 0,5 – 1,0 m, natomiast na obszarach wierzchowinowych dochodzi do 3,0 m. Kierunek spływu wód podziemnych pokrywa się w skali lokalnej z nachyleniem terenu
